— This paper presents a network adapted selective frame-dropping algorithm for streaming media over the Internet, which aims to address the problem of random packet losses resulted from network bandwidth mismatching. The basic idea is to first determine a sending window for each GOP according to its rendering time interval, and then selectively drop some(More)
With the improvement of network bandwidth, multimedia services based on streaming live media have gained much attention recently, among which IPTV has become a hot topic. After emergence of Peer-to-Peer (P2P) technology, P2P based IPTV systems are deployed widely. However, there exists a huge challenge, which is how to manage content. Digital Rights(More)
Most existing methods of stereo matching focus on dealing with clear image pairs. Consequently, there is a lack of approaches capable of handling degraded images captured under challenging real situations, e.g. motion blur is present and an image pair is in different illumination conditions. In this paper we propose a novel approach to handling these(More)
Technology advancements are allowing more and more new media applications and services to be delivered over the Internet. Many of these applications and services require flexibility in media distribution as well as security in protecting the confidentiality of media content and ensuring its authenticity. However, achieving flexibility and achieving security(More)
Generating virtual views is one of the crucial problems for a free-viewpoint video system. In this paper, we solve the problem by using a method based on the technique of view morphing, and construct a multi-camera based experimental free-viewpoint video platform to validate its feasibility. This method requires no setting up of dense cameras, therefore the(More)
